Hi-End Component Set for F-150

Alright guys, my stock speakers are decent in my truck but i'm ready to move up. I don't have the room for subs so i think I'll upgrade my speakes instead of adden some subs. I don't know a lot when it comes to speakers so bear with me. I have a 03 F-150 which has stock 5X7's. I have been told that one can make 6.5's fit. First off is this true and can it be done easyly?? If so I've been searching ebay looking for some comp sets. Here's what i've come across that have caught my eye...

I'd like to keep them under $200 if possible. The reason for this is that i would also need to by an amp to power them. What ya'll think. I have also been thinking about the XXX mids but i'm not sure how much they'd set me back.
